16-year-old from the Toronto area used a supercomputer system to find a new drug combination that shows potential in treating the genetic disorder cystic fibrosis, and won top honors for his work.

Marshall Zhang, an 11th-grade student at Richmond Hill's Bayview Secondary School, received first place Tuesday (May 10) in the 2011 Sanofi-Aventis BioTalent Challenge, a contest in which students conduct their own research projects with the help of mentors.

Cystic fibrosis is a potentially fatal condition caused by a genetic mutation, or error. It causes thick, sticky mucus to build up in the lungs and elsewhere. Cystic fibrosis occurs most among white people of northern European ancestry, in about 1 out of 3,000 live births. In the past, most people with cystic fibrosis died in their teens, according to the Mayo Clinic. It has no cure.

That ought to look pretty good on his med school application. :cool:

I can't help but wonder if Big Pharma using supercomputers to crunch the same sort of analysis that boy wonder conducted. Starting with patent-expired drugs alone, there's probably a lot of promising new applications for them.
 
The toughest animal on Earth...

"In 2007, a little known creature called a tardigrade became the first animal to survive exposure to space.

It prevailed over sub-zero temperatures, unrelenting solar winds and an oxygen-deprived space vacuum."

It's the (not so ferocious) water bear, otherwise known as the tardigrade.

Most of them are a whopping 0.3 to 0.5 mm long.

They can survive...

-temperatures between -272 C (one degree above absolute zero) to 151 C.
-pressures between the vacuum of space and 6000 atmospheres (six times the water pressure in the deepest ocean trenches.)
-dehydration (dessication)for up to ten years
-radiation of up to 5000 Gy (gray units) with 5-10 Gy being fatal to humans.

The water bear, Echiniscus granulatus

One of the experiments on board the final shuttle mission (Endeavor) right now is an Italian project called Biokis, which will determine the impact of short-duration spaceflight on a number of microscopic organisms.

"One of these experiments, the Tardkiss experiment, will expose colonies of tardigrade to different levels of ionising radiation, determined using an instrument called a dosimeter, at different points during the spaceflight mission.

The results from Tardkiss will enable researchers to determine how radiation dosage effects the way cells work.

Tardigrades are of particular interest following the 2007 European Space Agency (Esa) Foton-M3 mission, during which their ability to survive space conditions was discovered."

If we can make a suit out of those uglies we'd never have to worry about radiation again!
 
Anchor Away for Blackbeard’s Pirate Flagship

The jewel of Blackbeard’s fleet, Queen Anne’s Revenge ran aground off the coast of North Carolina in June 1718. Now, nearly 300 years later, archaeologists and marine technicians are painstakingly bringing relics from the legendary wreck to the surface, hoping to piece together the ship’s history and a picture of what daily life was like for 18th-century pirates. Yesterday, the team announced plans to hoist up the largest artifact to date: a 3,000-pound iron anchor that sits atop a potential goldmine of treasures containing cannons, plant materials and traces of the once-mighty wooden hull.
